ATTACHMENT FOR CLOSURE-DISK-MANUFACTURING MACHINES.

Specification of Letters Patent.

Patented Nov. 16, 1915.

Original application filed March 12, 1913, Serial No. 753,866. Divided and this application filed July 22,

' 1914. Serial No. 852,430.

To all whom it may concern:

Be it known-that I, HARRY L. COMPTON, a citizen of the United States, residing at Washington, District of Columbia, have in vented certain new and useful Improvements in Attachments for Closure-Disk- Manufacturing Machines, of which the following is a specification.

This invention relates to certain improve-.

'SerialNumber 753,866, and the particular object of this invention is to provide mechanism for preventing congestion of the closure disks in the passage between the discharge from the disk making machine and paraflining mechanism and for insuring delivery'of said disks in the proper position to the parafiining mechanism.

The invention consists in certain novel features in construction and in combinations and arrangements as more fully and particularly set forili and specified hereinafter.

Referring to the accompanying drawings;- Figure 1, is a vertical sectional view through a portion of a disk making machine, parafiining mechanism and mechanism involving my invention for delivering the disks from said machine to said paraflining mechanism. Fig. 2, is a detail top plan view of the mechanism of my invention. Fig. 3, is a detail side elevation thereof. Fig. 4, is a detail perspective somewhat diagrammatically illustrating certain parts.

" In the drawings, I show an upright bed or frame 1, mounted on and rising from a pedestal 2. The bed 1, carries disk making mechanism involving generally the elements and arrangements approximately as disclosed by Patent No. 927,002 issued July 6,

I 1909, to American Dairy Supply-Co. as the assignee of F. L. Nichols for machine for making cover or closing disks.

In this machine a ribbon of disk stock a, is fed with a step by step movement under the vertically movable punch 6, and over the annular die 9, and the punch and die c0- operate in cutting the complete disks from the ribbon of disk stock. The die 9, is formed in or carried by the die block 10,

and this die block is formed with a vertical discharge passage 11 (surrounded at its upper end by die 9) opening through the under side of the block. The punch 6 cuts out the disks and forces them down into said discharge passage, so that disks are dropping from the lowerend of the passage as the freshly cut disks are forced into the upper end of the passage.

If the completed disks are to be treated with material (paralfin for instance) to render them non-absorbent, I provide suitable mechanism for this purpose. For instance, in the particular example illustrated, I show an open top paraffin pot 12, pro vided with suitable means for supplying the necessary heat to keep the parafiin in liquid condition. This pot is arranged in front of the pedestal and is usually secured thereto and supported thereby below the level of the discharge end of passage 11, and a distance in front thereof. In the pot I show a horizontal transversely arranged rotary paraflining roll 13, having an absorbent material surface dipping into the liquid parafiin in the pot. This roll is carried and driven by a suitable shaft 14, carried by the pot and extending to the exterior of the ends thereof. 'At one end this shaft is provided with pulley 15, to which power is applied for rotating roll 13, so that its up per surface will move forwardly.

An absorbent material-surface parafiining and pressure roll 16, is arranged above and cooperates with and is driven by roll 13. The pressure roll shaft is carried by adjustable boxes confined in brackets 17, fixed to and rising from the pot ends. A stripper roll 18, is shown engaging the upwardly moving rear side of the paraffin roll 13, to remove surplus paraffin therefrom.

Means are provided for receiving the completed disks discharged from the lower end of passage 11, and delivering the same one at a time onto the forwardly moving lid upper surface of the paraffining roll 13, so

that the disks will be carried forward between the paraffin saturated surfaces of rolls 13, 16, and will absorb the desired' porting brackets 21, secured to any support such as the bed 1, orthe pedestal2. The chute is also supported by the transverse rotary cross shaft 22, mounted in and passing through the lower end of frame 20, and mounzted in and supported by the brackets-l v The upper end of the frame 20 is formed with longitudinal slots, receiving the transverse shaft 28, which. is adjustablelongitudinally of the chute and is held in the desired adjustment by adjusting and stop screws 24-. This shaft 23, carries idler roll 25, mounted to rotate on the shaft between the longitudinal sides of frame 20. This rotating roll is located directly below the discharge passage 11, so that the disks falling from said passage will drop onto said roll and be thereby directed forwardly in the chute. The upper surface of this roll 25 is moving forwardly and the disks are thereby thrown forwardly and properly started on their course down the chute. The roll is intended to prevent the disks wedg- -ing or becoming congested at the upper end 40 of'the chute, and'alsoto prevent the disks assuming vertically. disposed or edgewise positions at the upper end of the'chute. I

arrange an endless traveling flexible diskpropelling connection centrally and longitudinally of the chute and extending from the roll 25 to the shaft 22. In the particular example illustrated, this connection is formed by a comparatively narrow chain 26 mounted on the roll 25, and on a roll 27, fixed ,on the shaft 22. The roll 27 is located'in aslot or opening in the lower end portion of the floor of the chute and corresponds to roll 25. These rolls 25, 27, have central annular reduced portions receiving said chain and, containing the sprocket wheels 28, on which the chain is mounted. The upper ply of the chain travels downwardly on the floor of the chute while the lower ply of the chain returns below the chute. The chain is driven by shaft22, and can be tightened or loosened by adjusting shaft23, through the medium of screws 24:.

The, chain tends to maintain the disks in flat position in the chute and propels the disks downwardly and prevents them from congesting or unduly collecting in the chute. The lower end 29 of the chute floor, below roll 27, overlaps the paraifining roll 13, and delivers the disks thereonto. The forwardly moving surface of the lower roll 27, imparts the final propelling movement to the disks to carry them to the paraiiining rolls. The propelling devices are particularly designed to prevent congestion of the disks between the discharge from the punch and the paraflining rolls, and to cause delivery of the disks one at atime and in flat or approximately horizontal position to said rolls.

Any suitable means can be provided for driving the disk propelling chain, although in the present instance, I show the same driven from the parafiining roll shaft 14-, by driving connection 30, mounted on suitable sprocket wheels on shafts 14: and 22.

It is evident that my invention is not limited to handling closure disks or caps, and it is also obvious that various changes, variations and modifications might be resorted to without departing from the spirit and scope of the invention and hence I do not wish to limit myself to the particular mechanical expression of my invention disclosed hereby.

What I claim is;

1. In combination, a disk making machine having a vertical discharge from which the disks successively drop, an inclined chute extending downwardly from a point below said discharge and at its upper end arranged to catch the disks from said discharge, and an endless disk propelling conveyer having its downwardly traveling top ply arranged longitudinally on the floor of said chute.

2. In combination, an elongated longitudinally inclined chute having a longitudinal disk-receiving slideway and longitudinal edge walls, rotating rolls arranged transversely of the end portions of said slideway and having their upper disk-propelling surfaces exposed above said slideway, and an endless disk propelling conveyer extending between and driven by said rolls and having its upper ply arranged longitudinally ofand traveling downwardly along said slideway.

3. A pair of horizontally disposed cooperating rolls, means for cutting disks and dropping the same vertically from the discharge, and a downwardly inclined slideway leading from said discharge to said rolls and provided with an endless longitudinally arranged chain having its upper ply movable downwardly along said slideway and approximately centrally thereof, all combined substantially. as described.

4. In combination, means for forming disks and dropping the same from a discharge, a downwardly inclined slideway having its upper end arranged beneath said discharge to receive said disks, a roll arranged transversely in said slideway im: mediately below said discharge to receive the disks dropping therefrom, and an endless disk propelling convever arranged longitudinally in said slideway.

5. A disk making machine provided With a pair of horizontallyrdisposed cooperating rolls and a slideway to convey the disks to said rolls, said slideway provided With rotating rolls forming a portion of the floor thereof and an endless chain between said rolls and arranged longitudinally and approximately centrally of the slideway to prevent congestion of the disks therein.

'6. In combination, an inclined chute, transversely rotating rolls in the end portions of said chute, the roll at the upper end of said chute having circumferential portions exposed to engage disks dropped into the upper end of the chute, and an endless disk propelling conveyer driven by said rolls and having its upper ply arranged longitudinally and movable downwardly in said chute.

In testimony whereof I aflix my signature inpresence of two Witnesses.
